One assessment opthamologists do is the visual field test. While staring intently at a bright dot in the centre of a screen, dots of lesser intensity appear at various places around it. When you see one, you activate a clicker. If your peripheral vision is poor, it may indicate glaucoma and/or other things.
In your organization and industry, what do you sense is going on beyond the place you are focussing? What might you be missing? How will you train up your leadership peripheral vision?
